Calculate values such as rolling circumference differences, speed deviations, changes in ground clearance, tire diameter, rim width, track width changes or the use of spacers for adjusting the offset (ET calculator) and find out which tires or wheels are best suited for your vehicle. You will also receive a helpful graphical representation.

If you meant something else by “FPse activator” (e.g., a license bypass tool), I can’t help with that — but for a legitimate enhancement feature, the above is a solid start.
If the idea of paying or dealing with activation frustrates you, remember that FPse is not the only PS1 emulator on the block. Consider these legitimate alternatives (which also require payment or open-source donations):

Note the difference in rolling circumference:
Rolling circumferences are generally approved in the range +1.5% und -2.5% g. Please check with the responsible inspector beforehand.
